There is the potential for severe thunderstorms, including the risk of isolated tornadoes, Thursday from the part of the Carolinas to central and northern Virginia.
The storms are firing ahead of a zone of torrential rainfall that is advancing slowly through the Appalachians and southern Atlantic Seaboard.
Cities that can be hit with a thunderstorm containing damaging winds, hail, flash flooding and even a tornado include Charleston and Myrtle Beach, South Carolina; Raleigh and Fayetteville, North Carolina; and Charlottesville, Richmond and Lynchburg, Virginia.
If the sun emerges farther north, storms could also become severe in part of northern Maryland, the eastern West Virginia Panhandle and a portion of south-central Pennsylvania.
People living in or traveling through these areas should keep an eye out for rapidly changing weather conditions. Storms will cross portions of the I-40, I-64, I-66, I-70, I-81 and I-95 corridors. Motorists should be alert for sudden low visibility and powerful wind gusts.
There is the possibility of an isolated tornado, which could be concealed by heavy rain.
The storms will weaken as they move farther to the east later Thursday night, but windswept rain will continue. Locally strong thunderstorms with gusty winds may ignite ahead of steady rain from part of Delmarva to New Jersey and southeastern New York state on Friday.
